slimmest and most thermally efficient folding glass wall

NanaWall’s booth at this year’s International Builders Show was all the buzz as the next generation folding glass wall was launched. Featuring the slimmest and most thermally efficient aluminum framed system, NanaWall NW Aluminum 840 brings forth a new level of minimalist aesthetics while providing strong weather resistance.

Show attendees were able to physically measure the thinness of the aluminum frame—a mere 3 7/8” (99 mm) at the intersection of two folding panels. With over 30 years of heritage, NW Aluminum 840 is a culmination of limitless innovations grouped into a single glass wall system.

From Real Estate to Fenestration

Working from a small room, the four Nana brothers divided their time between real estate development endeavors and pioneering the category of folding glass walls within the fenestration market. In 1986, NanaWall successfully launched its first product into the market—a classic wooden four-paneled folding wall—pursuing a mission to create and deliver flexible solutions for large architectural openings.

In 1993, NanaWall sold ten classic wood systems to different Starbucks locations who had originally expressed interest in aluminum doors—not yet offered by the developing company. Striving to meet customer needs, NanaWall set out to advance the design possibilities for any space possible that would lead them to Germany and a partnership with Solarlux. This joint venture offered access to more tools, advanced technologies, and increased production capacity.

From innovation to innovation, each addition has paved the way for better enhancements and patented features. From hurricane approved glass wall systems to sound-buffering features offering ratings up to STC 45.
